Scientific evidence such as reflection and photoelectric effect has proven the wave-particle model of electromagnetic radiation to be true.

<h3>What is electromagnet radiation?</h3>

Electromagnetic radiation is radiation produced as a result of the interactions of the electric and magnetic fields.

Some forms of electromagnetic radiation include:

radio waves
microwaves
ultraviolet radiation
visible light

Electromagnetic radiation can be described using a wave model or a particle model.

The wave property of electromagnetic radiation include:

diffraction
reflection
refraction

The particle property of electromagnetic radiation include:

photoelectric effect
Compton effect.

Therefore, the wave-particle model of electromagnetic radiation is correct because it can be backed up by experiments and evidence.

Answer:

I just took the identifying Claims Quick check

Explanation:

1. Claim: Electromagnetic radiation can be described by a wave model or a particle model, depending on the situation.

Is this a scientific claim?

Yes, it can be backed up by experiments and evidence.

2. A student states, "The wave model is better than the particle model for electromagnetic radiation because it is easier to understand." Is the student's statement a scientific claim?

No, it isn't because the statement is an opinion.

3. A student wants to make a scientific explanation regarding the wave model of electromagnetic radiation. Which of the following would be part of the scientific explanation?

Claims

4. A student makes this statement before conducting an experiment on electromagnetic radiation: "We expect the laser to diffract when passed through a slit." Which of the following explains why the student's statement is not a claim?

It is a prediction or hypothesis.

5. Which claim do scientists use to describe electromagnetic radiation?

Electromagnetic radiation exhibits properties of both particles and waves.

6. A physician is going to use high-frequency electromagnetic radiation to treat cancer in a patient. Which is a claim about this event?

A wave model is most useful for describing the frequency of the radiation.

a small negatively charged sphere with a mass of 5.4*10^-5 is suspended between two parallel plates. the potential difference is

labwork [276]

Here, Fe = Fg
q.E = m.g
We have: E = 360 V
m = 5.4 × 10⁻⁵
g = 9.8 m/s² [ constant value for earth system ]

Substitute their values into the expression:
q (360) = 5.4 × 10⁻⁵ × 9.8
q = 52.92 × 10⁻⁵ / 360
q = -1.47 × 10⁻⁶ [ negative sign represents the nature of charge ]

So, Your Final answer would be 1.47 × 10⁻⁶

Hope this helps!

Find a) molar fraction, b) concentration in mol / and c) concentration in mol / kg of an aqueous solution with 25% alcohol: the

igor_vitrenko [27]

Explanation:

Answer

( 58.3 mL ) (

0.789 g

1 mL

) (

1 mole

46 g

) = 1 mole C2H5OH

( 500 mL H2O ) (

1 g

1 mL

) (

1 mole

18 g

) = 27.8 mole H2O

The total moles = 1 mole C2H5OH + 27.8 mole H2O = 28.8 moles

The mole fraction =

moles C2H5OH

total moles

1 mole C2H5OH

28.8 total moles

= 0.035

The mole percent would be 3.5%.

What is the weight fraction?

Answer

( 58.3 mL ) (

0.789 g

1 mL

) = 46 g C2H5OH

( 500 mL H2O ) (

1 g

1 mL

) = 500 g H2O

The total mass = 46 g C2H5OH + 500 g H2O = 546 g

The mass fraction =

mass C2H5OH

total mass

46 g C2H5OH

546 total grams

= 0.084

The mass percent would be 8.4%.

What is the molarity?

Answer

The molarity =

moles C2H5OH

L of solution

1 mole C2H5OH

.5583 L

= 1.79 M

What is the molality?

Answer

The molality =

moles C2H5OH

kg of solvent

1 mole C2H5OH

0.5 kg H2O

= 2
